Arghh I'm really fed up of opks.
Last month I had a positive ovulation test on cycle day 18, the month before it was cycle day 13.
So far I'm on cycle day 11 and my tests are already pretty strong - not a peak yet but they really don't look far off. Yesterday on cycle day 10 they were pretty strong too.
My cycle lengths vary from around 29/30-35 days. Obviously the later I ovulate the longer my cycle is.
Is this normal fluctuation?! Have been ttc and tracking ovulation for 8 months.
I'll attach a photo of tonight's opk
